That load cell has a miniscule sensitivity. You need an amplifier of some sort...either a stand-alone amp or something like the HX711 with integral PGA. DaveEvans June 2, 2017, 5:54pm #4. Or, if you happen to have a Mega2560, you could use its ADC in differential mode, with its PGA set to 200, and with the internal reference voltage Like most Arduino-compatible ICs, a breakout board for HX711 is readily available: To use the HX711 with the bar load cell, we just connect the output wires White and Green to the A+ and A- pins.

In this project we will be interfacing HX711 Load cell amplifier with Arduino and 16*2 LCD for designing Arduino Weighing. . Yes, In general. Each load cell is designed to output more or less the same signal for 100% load. So a 100g load cell and a 500kg load cell will both put out the same signal at their maximum load. That said you have to look at the 500kg load cell specification and see if it is appropriate to use the HX711.
The first step is to test the low end of the weight scale and you can do this without adding load to the load cell. So the variable loadLow in Arduino sketch code can be assigned 0 as for zero grammes. Then copy the smoothed analogue value to the analogLow variable and move on to the next step Apply pressure to the load cells (all of them at once) and observe a change in the voltage between A+ and A-. Assuming that is showing good results (the voltage change will be quite small, so set your DMM to its most sensitive setting), your next point of call is the connection to the Arduino itself

Let's start! Hardware Required. Arduino Uno; 50kg Half-Bridge Load Cell; HX711 (Weight Sensor Amplifier + 24 bit ADC) modul To install the servo, simply slide it into the housing. The servo should be oriented for the motor shaft to be closest to the load cell. The servo's wire will come out through a hole behind the load cell. It can be plugged into the Arduino from there. To secure the servo into place, use at least two M4 x 6mm screws
Hi, I'm trying to connect Atmega328p with Load cell through HX711 I've tested components using the Arduino IDE and a HX711 Lib and everything works fine.

Any help would be appreciated HX711 Load cell Module. Fixing Load Cell with Platform and Base: This step is optional and you can directly put the weights on the Load cell without Platform and can simply clamp it without fixing it with any base, but it's better to attach a platform for putting the large things on it and fix it on a Base so that it stand still
It is this object that is your interface to the HX711 physical device. To use two of them you first need to have two objects - one for each HX711. You can name them whatever you like. For example: HX711 scale1; HX711 scale2; The line: scale.begin (DOUT, CLK); is where it tells the HX711 object which pins the HX711 chip is connected to See more: source code ftp file using inet control, vb6 source code web page using internet control, flow control using, code flow control using, labview using load cell output, write program code udp using flow control, project-17-stepper-motor-direction-control-using-2-buttons-with-the-arduino, arduino load cell hx711 code, weight measurement.
